PRECAUTIONS
A single switch can be used to supply power to units on the
same system. However, branch switches and branch circuit
breakers must be selected carefully.
For a group control remote controller, choose the remote
controller that suits the indoor unit which has the most functions.
Do not ground the equipment on gas pipes, water pipes,
lightning rods or crossground with telephones. Improper
grounding could result in electric shock.
F
IELD SETTING
Field setting must be made on the remote controller in function of the
installation condition.
Setting can be made by changing the "Mode number", "First
code No." and "Second code No.".
For setting and operation, refer to the "Field settings" in the
installation manual of the remote controller.

Note 1 : Setting is carried out in the group mode, however, if the mode number inside parentheses is selected,
indoor units can also be set individually.
Note 2 : Factory settings of the Second code No. are marked in grey backgrounds.
Note 3 : Only use in combination with optional remote sensor or when setting 10-2-03 is used.
Note 4 : If group control is selected and remocon sensor is to be used, then set 10-6-02 & 10-2-03.
Note 5 : If setting 10-6-02 + 10-2-01 or 10-2-02 or 10-2-03 are set at the same time, then setting 10-2-01,
10-2-02 or 10-2-03 have priority.
Note 6 : If setting 10-6-01 + 10-2-01 or 10-2-02 or 10-2-03 are set at the same time, then setting for group
connection, 10-6-01 has priority and for individual connection, 10-2-01, 10-2-02 or 10-2-03 have
priority.

Control by 2 Remote Controllers (Controlling 1 indoor
unit by 2 remote controllers)
When using 2 remote controllers, one must be set to "MAIN" and the
other to "SUB".
MAIN/SUB CHANGEOVER
Insert a wedge-head screwdriver into the recess between the
upper and lower part of the remote controller and, working from
the 2 positions, pry off the upper part. (See figure 14)
(The remote controller PC board is attached to the upper part of
the remote controller.)
Turn the main/sub changeover switch on one of the two remote
controller PC boards to "S". (See figure 18)
(Leave the switch of the other remote controller set to "M".)

Input "off" enables control
3 How to select forced off and on/off operation
- Turn the power on and then use the remote controller to
select operation.
- Set the remote controller to the field set mode. For details,
refer to the chapter "How to set in the field", in the remote
controller manual.
- When in the field set mode, select mode No. 12, then set the
first code No. to "1". Then set second code (position) No. to
"01" for forced off and to "02" for on/off operation. (forced off
at factory set.) (See figure 19)

Centralized control
For centralized control, it is necessary to designate the group No. For
details, refer to the manual of each optional controller for centralized
control.
